Description

TECHNICAL FIELD

The present disclosure relates to the technical field of suction equipment, in particular to an integrated vacuum suction pad.

BACKGROUND ART

With continuous development of a building technology, now a large area of curtain wall structures can be constructed on surfaces or internal of a building to enhance the aesthetic effect of the building. Curtain walls are generally composed of a plurality of large building materials jointly; corresponding high-altitude installation equipment is required in order to install these building materials at a specified position, and such high-altitude installation equipment mostly adopts pads to adsorb and grab the building materials.

A vehicle-mounted mobile elevating work platform for glass installation, with an application number of 202022152195.5 and disclosed by China National Intellectual Property Administration, comprises a vehicle-mounted mobile platform chassis, a rotating base, lifting arms and a glass adsorption rack, and is characterized in that the vehicle-mounted mobile elevating work platform for glass installation further comprises a coarse adjustment mechanism, a fine adjustment mechanism and a middle adjusting arm connected between the coarse adjustment mechanism and the fine adjustment mechanism; and the coarse adjustment mechanism is connected with the lifting arms at the same time, and the fine adjustment mechanism is connected with the glass adsorption rack at the same time. Although a technical solution of the patent provides the high-altitude installation equipment, in the technical solution of the patent, adsorption equipment is composed of a plurality of pads jointly, while adsorption actions of these pads are controlled by a vacuum pump in a unified mode. Consequently, if the vacuum pump or related components are damaged, the whole adsorption equipment will be failed; and if the adsorption equipment malfunctions in operation, dangerous accidents easily occur. Meanwhile, in case of damage, the whole adsorption equipment can only be replaced, and therefore a maintenance cost is increased greatly.

In practical use, the integrated vacuum suction pad is installed on the adsorption rack of the high-altitude installation equipment. The vacuum pump and the control valve can be powered on by the relay. When the building material needs to be adsorbed, the adsorption part is communicated with the vacuum pump by the control valve. The vacuum pump is started to pump out the air between the adsorption part and the building material, so that the adsorption part is adsorbed onto the building material, and then the building material can be driven to move by other devices of the high altitude installation equipment. When the building material needs to be released, the control valve can be controlled for communicating the adsorption part with the atmosphere, so that a position between the adsorption part and the building material is filled with the air again, and accordingly the adsorption part can be separated from the building material. In conclusion, according to the present disclosure, the pad is integrated with the devices, such as the vacuum pump, and each pad is capable of doing adsorption and release actions independently. Therefore, in a working process, when one or some of the pads are failed, the building material will not be released instantaneously, so that the working safety is improved effectively. Meanwhile, the damaged pad can be maintained and replaced independently, so that a maintenance cost is reduced effectively, and a maintenance process is simplified.

DETAILED DESCRIPTION OF THE EMBODIMENTS

The following embodiments are only used for explaining the present disclosure, and are not intended to limit the present disclosure; modifications made by those skilled in the art without involving inventive contribution after reading this specification are all protected by the patent law as long as the modifications fall within the scope of the claims of the present disclosure.

FIG. 1 illustrates an integrated vacuum suction pad of the present disclosure, and the integrated vacuum suction pad comprises an adsorption part 1, a vacuum device, a protective box 3, a vacuum tank 4, a mounting part 5 and a filter 6; the protective box 3, the vacuum tank 4, the mounting part 5 and the filter 6 are fixedly arranged on one side of the adsorption part 1, and the vacuum device is arranged in the protective box 3, so that the vacuum device is protected by the protective box 3. The vacuum device is communicated with the vacuum tank 4, and the vacuum tank 4 is communicated with the adsorption part 1 by the filter 6; the mounting part 5 is arranged between the protective box 3 and the vacuum tank 4; and the mounting part 5 comprises connecting struts 51, a connecting plate 52 and springs 53. The four connecting struts 51 are provided, and are arranged at four top corners of a rectangle respectively. One end of each of the connecting struts 51 is fixedly connected with one side of the adsorption part 1. A U-type plate used for connecting with other components of the high-altitude installation equipment is fixedly arranged on the connecting plate 52. The four connecting struts 51 respectively penetrate through the four top corners of the connecting plate 52 and are connected with the connecting plate 52. At the moment, the connecting plate 52 is parallel to the adsorption part 1. One end of each of the springs 53 is in contact with each of the connecting struts 51, and the other end of each of the springs 53 is in contact with the connecting plate 52. When the adsorption part 1 is pushed by an external force, the force born by the adsorption part 1 is transmitted to the connecting struts 51, so that the springs 53 are compressed. At the moment, the connecting struts 51 and the connecting plate 52 do relative motion, and the spacing between the adsorption part 1 and the connecting plate 52 is changed. When the external force disappears, the springs 53 stretch, so that the adsorption part 1 and the connecting plate 52 are reset.

The protective box 3 comprises a mounting frame 31 and a protective cover 32, wherein the mounting frame 31 is connected with the adsorption part 1, and the protective cover 32 is connected with the mounting frame 31, so that the interior of the mounting frame 31 is in an approximately closed state. The mounting frame 31 comprises a mounting plate 312, the mounting plate 312 and the adsorption part 1 are parallel to each other, and are arranged at intervals. The mounting frame 31 further comprises a drainage plate 313, and the drainage plate 313 extends from the end, far away from the adsorption part 1, to the other end, close to the adsorption part 1, of the mounting frame 31, and is connected with the mounting plate 312. Meanwhile, the end, far away from the adsorption part 1, of the drainage plate 313 is bent, so that a gap is formed between the drainage plate and the inner wall of the protective cover 32, and thus the drainage plate and the protective cover can form an approximate groove structure jointly. Two connection modes are provided, which are between the mounting frame 31 and the adsorption part 1, and between the protective cover 32 and the mounting frame 31. The first connection mode: set screws 11 are fixedly arranged on the adsorption part 1, and the mounting frame 31 is connected with the adsorption part 1 by the set screws 11. Meanwhile, after the mounting frame 31 is connected with the adsorption part 1, the set screws 11 protrude out of a surface of the mounting frame 31. The protective cover 32 is connected with the mounting frame 31 by the set screws 11. In this connection mode, the protective box 3 can be connected with the adsorption part 1 more stably. However, the set screws 11 are liable to break, and the damaged set screws 11 easily cause that the whole protective box 3 cannot be maintained and replaced normally. The second connection mode: as shown in FIG. 3, the mounting frame 31 is directly connected with the adsorption part 1 fixedly, and connecting parts 311 through which the screws can penetrate are arranged on the mounting frame 31; and the protective cover 32 is connected with the mounting frame 31 by the connecting parts 311. As the connecting parts 311 are only used for connecting the protective cover 32 with the mounting frame 31, and the screws on the connecting parts 311 can be directly installed and removed, the replacement is easier in this connection mode when part of components are damaged. The second connection mode is preferably in this embodiment.

FIG. 4 illustrates a vacuum device comprising a vacuum pump 21, a control valve 22 and a relay 23, the vacuum pump 21 is communicated with the vacuum tank 4, and the relay 23 is connected with the vacuum pump 21 and the control valve 22 electrically. The vacuum pump 21 is fixedly arranged on the mounting plate 312; as the mounting plate 312 is spaced apart from the adsorption part 1, vibration generated by other components during adsorption of the building material is effectively prevented from being transmitted to the vacuum pump 21, so that the vibration at the vacuum pump 21 is reduced, and thus a fault probability of the vacuum pump is reduced. Meanwhile, the control valve 22 and the relay 23 are installed on the side, far away from the adsorption part 1, of the vacuum pump 21, so that the vacuum device is in an approximately suspended state in the protective box 3.

Preferably, the vacuum device further comprises a measuring instrument 24 used for measuring an air pressure of the vacuum tank 4, so as to achieve automatic control over the vacuum pump 21 according to measured results; a window corresponding to the measuring instrument 24 is formed in the protective cover 32, so that maintenance personnel can read values of the measuring instrument 24 from outside for maintenance.

In practical use, a plurality of the pads of the present disclosure can be jointly installed on the same high-altitude installation equipment by the connecting plate 52 to form an adsorption device. If the building material needs to be adsorbed, the adsorption part 1 is attached to the building material to be adsorbed. Due to influences of a mounting error, a part of the adsorption part 1 is liable to be earlier attached to the building material than the other part of the adsorption part 1 does in an alignment process. At the moment, the earlier attached part of the adsorption part 1 is subjected to a reaction force from the building material, and under the action of this reaction force, the springs 53 on the connecting struts 51 are compressed, so that the spacing between the connecting plate 52 and the adsorption part 1 is changed, and thus the other part, to be attached to the building material, of the adsorption part 1 can be attached to the building material properly. Therefore, an error-tolerant rate in practical operation is increased. After completion of attachment, the vacuum pump 21 is controlled to pump out air from the vacuum tank 4, and the adsorption part 1 is controlled by the control valve 22 to be communicated with the vacuum tank 4, so that a negative pressure in the vacuum tank 4 can be applied to the position between the adsorption part 1 and the building material, and thus the building material can be adsorbed by the adsorption part 1. Meanwhile, in the adsorption process of the adsorption part 1, the air flowing into the vacuum tank 4 from the adsorption part 1 is filtered by the filter 6 to prevent external impurities from entering the vacuum tank 4. After the adsorption part 1 is fully adsorbed onto the building material, external air cannot enter the vacuum tank 4, so that the vacuum tank 4 can be kept in a negative pressure state for a certain duration. At the moment, the vacuum pump 21 can be controlled to stop working. Therefore, by taking advantage of the vacuum tank 4, on one hand, the working time of the vacuum pump 21 can be reduced effectively, so as to reduce the fault probability of the vacuum pump 21 and prolong the service life of the vacuum pump 21; and on the other hand, if the vacuum pump 21 stops working due to a fault, the vacuum tank 4 can still maintain the adsorption state of the adsorption part 1 to prevent the adsorption part 1 from being separated from the building material suddenly, so that the safety is improved. When the building material needs to be released, the adsorption part 1 can be communicated with the atmosphere by the control valve 22, and therefore the negative pressure between the adsorption part 1 and the building material can be fractured without reverse inflation for the vacuum tank 4, so that the adsorption part 1 can be separated from the building material properly. Therefore, the control valve 22 can be used for fast switching the pressure state between the adsorption part 1 and the building material, on one hand, the working efficiency is improved, and on the other hand, the control sensitivity is improved.

In conclusion, the pads of the present disclosure are capable of completing adsorption and release operations independently. In an actual state, when some of the pads are damaged, the working states of the rest pads are not affected. On one hand, the adsorbed building material in the working process can be effectively prevented from being released suddenly, and therefore the safety in work of the high-altitude installation equipment is effectively improved; and on the other hand, the damaged pad can be maintained and replaced independently, so that the maintenance cost is reduced greatly, and the maintenance process is simplified.

Meanwhile, in case of working in a rainy season, when rainwater falls onto the adsorption part 1, the rainwater will flow out of the protective box 3 through the gap between the mounting plate 312 and the adsorption part 1, and therefore the situation that the rainwater gathers in the protective box 3 and consequently the vacuum device is damaged is effectively avoided. The rainwater directly falling onto the protective box 3 is led by the drainage plate 313, and flows to the mounting plate 312 through the groove structure formed by the drainage plate 313 and the protective cover 32 jointly, and finally flows out of the protective box 3 through the gap between the mounting plate 312 and the adsorption part 1. Thus, the vacuum device can be effectively protected from soaking in external liquid by the protective box 3, so that the damage probability of the vacuum device is reduced, and the overall safety is improved.

The above descriptions are only implementations of the present disclosure, but the protection scope of the present disclosure is not limited thereto; any easily-thinkable equivalent modifications or substitutions made by those skilled in the art within the technical scope disclosed by the present disclosure shall fall within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure shall follow the protection scope of the claims.
